Forty-three  were  men  (69.35%)  with  a  mean  age  of  56.33  years.  The  medical  records  were  analysed,  especially  history,  operative  reports,  histopathology  reports, survival, adjuvant treatment and recurrence. &lt;\/br&gt;&lt;\/br&gt; &lt;b&gt;Results:&lt;\/b&gt; All patients underwent surgical treatment (33.87% also had partial removal of the lower jaw, 67.74% adjuvant radio-therapy, 11.29% radiochemotherapy). More than half reported to the doctor within 6 to 15 weeks from the onset of symptoms. The majority smoked and drank alcohol (96.32%). Five-year disease specific survival (DSS) was 68.69%. &lt;\/br&gt;&lt;\/br&gt; &lt;b&gt;Conclusions:&lt;\/b&gt; The age over 65 did not significantly influence DSS. The location on the anterior two thirds of the tongue gave the best outcome, while the worst outcome was observed in the retromandibular triangle area which was statistically almost significant (p = 0.06843). In the case of higher degrees of local and regional advancement and a higher stadium, a worse out-come was recorded. Positive surgical margins were identified in 11.29% of the cases, but they had no impact on the results of treatment. No worsening of the outcome was proven for the patients who reported to the doctor later than 15 weeks following the occurrence of symptoms.\n\n<\/jats:p>","DOI":"10.5604\/01.3001.0015.7567","type":"journal-article","created":{"date-parts":[[2022,6,9]],"date-time":"2022-06-09T10:21:30Z","timestamp":1654770090000},"page":"12-17","source":"Crossref","is-referenced-by-count":4,"title":["Oral squamous cell carcinoma \u2013 clinical characteristics, treatment, and outcomes in a single institution retrospective cohort study"],"prefix":"10.5604","volume":"76","author":[{"given":"Joanna","family":"Janiak-Kiszka","sequence":"first","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology with the Subdepartment of Audiology and Phoniatrics, Collegium Medicum of the Nicolaus Copernicus University in Bydgoszcz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magdalena","family":"Nowaczewska","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Laryngological Oncology with the Subdepartment of Audiology and Phoniatrics, Collegium Medicum of the Nicolaus Copernicus University in Bydgoszcz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wojciech","family":"Ka\u017amierczak","sequence":"additional","affiliation":[{"name":"Department of Human Physiology, Collegium Medicum of the Nicolaus Copernicus University in Bydgoszcz, Poland; Institute of Physiology and Pathology of Hearing in Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3689","reference":[{"key":"227343r1","unstructured":"www.onkologia.org.pl."},{"key":"227343r2","doi-asserted-by":"crossref","unstructured":"Giraldi L., Collatuzzo G., Hashim D. et al.: Infection with Human Papilloma Virus (HPV) and risk of subsites within the oral cancer.
